I'm going to hazard a guess and say that it is to do with elevation 
compensation. When the pressure is high, your readings are higher than 
analysis, and when low, lower. This can be caused by the wrong elevation 
entered into the console, or using an old version of the Davis software 
that reports the 'wrong' pressure.
